Maintenance Tips for a Modified Bitumen Roof Maintenance Tips for a Modified Bitumen Roof

A modified bitumen roof is an updated version of the flat asphalt roofing that is seen so much on commercial buildings. The asphalt roofs had to have gravel and rock on top to hold them down because they actually sat on top of the roof and were not connected to the roof as would be a tile roof. Modified bitumen roof has the same principal of the asphalt roofing except that modifiers have been added to the asphalt to make it become part of the roof and not to just sit on top of it. They are quickly becoming part of the industry and being used a lot in the residential homes. The old asphalt roofs needed a lot of maintenance due to weather conditions and the fact that they were not elastic enough.

Knowing How it Works Helps You Maintain It

The way this roof is put together is one of two ways that actually end up in the same manner. It is all in the application. The modifiers that are used in the asphalt and then combined with either fibers or fiberglass which makes it a stronger more weather proof part of the roof. These are put on in entire sheets that fit the roof and are applied one of four ways: heat, cold, heat weldable or self adhesive.

Checking for Leaks and Broken Welds

If your roof is put together in pieces, or heat welded together with separate pieces, these can sometimes come apart. You need to check the roof over for pieces pulled up from the roof. Or even pieces that are missing as can happen with bad weather and high winds. If you find a spot such as this you need to patch it with another piece heat applied to the roof and cover any wood that is exposed.

Checking for Holes and Rips

Another way that these roofs can be damaged is something falling on them and tearing holes such as a tree limb or palm tree pieces that are pushed by high winds. It may just be a tiny hole, but it is a potential leak. If you find such a hole, use the type roof you have repair instructions. Checking around the roof for any additional holes or tears, make sure to check around chimney and any vents that are on the roof.

Look Out for the Curling Edges

With the self adhesive applications of this type of roof, you always have a chance that the edges will pull up. Whether by bad application of the installer or strong storms and winds that will pull them up from the edges of the roof. This will be a bad place for leaks to start in. Any wind or rain coming in that direction will push it back even more. Repair this by applying the roofing cement to the exposed spot. Make sure there is no damaged wood underneath first. Then pull the piece back over making sure to push it over and around the edge of the roof to keep it intact. Check on it for a few days to make sure it stays intact.
